I have a 2003 GTI that I was given and had the engine rebuilt. The problem I am having is the battery is not recharging itself when I run it. I have a new battery in it and make sure it is fully charged before I take it out. It starts fine but I'll run it arounf for about an hour and it won't restart and I'll take it out and see that the battary has run down. I am not the most mechanically gifted person so I don't have a clue what to look for. I assume the ski does not have an alternator like a car - so what keeps the battary charging? What do I look for? Please help!

Battery loses it's charge

Welcome to the seadoo forum rip1957. I would check the wires from the battery to be sure they are tight. Here is some information on the charging system, and how to check it. You will need a multi meter to check it.
When the engine is running, set your voltmeter for 20 VDC and put the leads on the correct terminal posts. With the engine running, you should be reading anywhere from 14.5 to 14.8 VDC. (typically this test is done at 5,000 rpms) This tells you your charging circuit is good. If the voltage is higher, the regulator is bad. If you’re not showing a charge and you've replaced the rectifier, you may want to do a test on the Magneto/stator/charging coil. If you’re not a premium member and you don't have access to a manual, this test will be hard to do without it. There are 2 fuses that protect the charging system. Check the 15 amp fuse in the MPEM and the 15 amp fuse between the solenoid and the MPEM.
The magneto and stator create un-regulated AC current. The "rectifier" converts that AC to DC current and the regulator maintains the current between 14 to 14.5 volts DC for the engines operation and charging circuit.
I hope this information is a help.
